Hhhmmm...I think the definition of a narcissist is being taken very broadly here.
Now, the part about the codependent taking others' feelings personally does strike a chord with me. I know I did it in my marriage to my A. and he did it to me, probably even more so. But I don't see this as narcissism, as narcissists don't tend to be people-pleasers. They are self-pleasers to the very core, and to the detriment of others' feelings and needs.
